Hi,
I was just thinking of various types of signals that are used in communication systems. Mostly we use EMWaves for the purpose of communication.
For an example, consider FM/AM, these signals can be grabbed/catched by the Radio whenever the radio is inside a certain boundary (often of a circular type). Same as in the case of a mobile phones.
Whereas, when you consider a TV Remote(Infrares), it travels only in a particular direction.
My question is: How do you visualise the propagation of these signals?
Like, in a mobile network the signal traverses in all direction.
